KEY CASE Filed Jan. 22, 1931 15 15 14 i if ATTORNEY UNITED STATES PATENTowl-cs SEBASTIAN SGHMALZG-RUBER, OF ,BLOOMFIELD, CONNECTICUT KEY CASEApplication filed January 22, 1931. Serial No. 510;518.

My present invention has for its object to provide a key case of asimple, inexpensive nature in which the construction is the key hangersmay be gether or farther apart user,

thereby to allow for diiferent size such that placed closer toatithewill of the and thickness of keys without interfering with properplacement thereof in a compact mass when the together.

Further, it is an object to provi in which the hangers are mountedholder case is closed and secured de a case by means of a coil springheld in a rigid support and itself supported at intervals throughout itslength against misalignment, the coil spring being of sufficientstrength to retain the heads of the hangers agamst accidental detachmentwhile at the same time permitting them to freely swivel of the springand and be swung about the axis also-to permit them to be disconnectedfrom the spring when it is desired to change their location along thespring.

Further,

spring wholly of wire in Other objects will in part be u it is an objectof the invention to so form the heads of the holders that they will notbecome entangled with the coils of the and also enable the holders to bemade one piece each if desired. obvious and in part be pointed outhereinafter.

To the attainment of the aforesaid objects and ends, in the noveldetails of construction,

the invention still further resides combination and arrangement ofparts, all of which will be first fully described in the followingdetailed description, then be particularly pointed out in theappended'claims, referbeing had to the accompanying draw- Figure 1 is aplan of a case embodying the invention.

Figure 2 is an enlarged cross section there- 3 is an elevation of thehanger from the Figure 4 1s an elevation of the hanger portion shown inFigure 2 taken angles to that figure.

at right Figure 5 is .a detail perspective view of a portion of theinvention.

Figure 6 is adetail perspective view of one of the hangers.

Figure 7 is a plan of the blank of .the mounting plate.

Figure 8 is a similar view of ;a modified form of such blank.

Figure 9 is a section similar to Figure 2 showing the modified form .ofmounting :plate in position on the cover 4.

"In the drawing in which like numerals of reference indicate like partsin all of the figures, 1 represents the mounting plate which is providedalong one edge with a series of projections 2 bent into the formof eyesfor the reception of the coil spring 8, the spring being held againstlongitudinal movement out of the mounting plate by means offlugs 3 bentover at right angles after thezspring has been inserted. I 4 e Themounting plate 1 is-securred to a leather or other flexible back 4i bysuitable rivets 6 or otherwise, the back i being foldable and having itsfolded parts adapted to be held together .by snap fasteners 5in theusual --.,way.

It will be observed that the eyes 2 are spaced apart a greater distancethan the width of the eyes inorder to expose consider able lengths ofthe spring 8 {so that one'ior more hangers may be connected to {thespring between each pair of eyes 2 and at varying distances fromsaideyes as may be found idesirable. The spaces between the eyes 2 areindicated by 17in the drawing.

In order to keep down the expense of manufacture I prefer to make thehangers each of a single piece of wire and when so made theycomprise theshank 9, the head 12., the loop 10 and a suitable portion 11 to .engagethe shank 9 .to close the loop and prevent, keys from accidentally,becorning disconnected from the loop.

When made .of wire it is essential that the head 12 beso constructedasnot to catch or interlock with the coils of the spring 8 I and to thisend I form the head 12 by coiling the wire as at 13 and 14 and filingoff the end 15 and projecting it slightly into the eye of the head sothat there will be no points to catch on the coils of the spring 8. Theloop portions 13 and 14 are mashed tightly toether as shown in Figure 4,thereby is produced a knob-like head having a wedge-like portion at 15,see Figure 4 that will fit the interior diameter of the spring and be ofsufficient thickness not to accidentally pull out between adjacent coilsof the spring, and yet be of such construction that by exerting asufiicient force the head 12 may be pushed out between adjacent coils ofthe spring and inserted between other coils if desired so that thehangers which are located adjacent the eyes 2, may together as may befound desirable, in order to enable keys of various thickness and sizesto be compactly placed together without forming undue humps in the casewhen closed, an objection that is now so common in other cases ofsimilar type.

In Figures 8 and 9 those parts corresponding to similar parts in thepreceding figures bear the same numbers of reference plus the indexletter m.

From the foregoing description, taken in connection with theaccompanying drawing, it is thought the complete construction, 0 orationand advantages of my invention will be clear to those skilled in the artto which it relates.

What I claim is:

1. In a key case, a rigid supporting plate having spaced coil springretainin loops, a coil spring located in said loops with portionsthereof of substantial length located between the loops and exposed, anda set of key hangers having heads removably and swivelly and swingablylocated in said exposed coil portions, said hangers being pendent fromsaid coil spring, said hangers comprising wires having at one end keyloops and at the other end head loops coiled closely toether and havinga wedge-shaped portion or entering the spring in the insertion andremoval of the hanger.

2. In a key case, a rigid supporting plate having spaced coil springretaining loops, the spaces between the loops being of greater lengththan the width of the loops, a coil sprlng located within said loopswith substantial portions exposed between the loops, and a set of keyhangers each of which comprises a rod-like body having one end coiledthrough approximately 500 to constitute a head, the coiled end of thewire being bevelled and mashed flat against the remainder of the coiledportion to provide a wedge-shaped entering part of the wire forintroduction between and removal from the coils of the spring,substantially as specified.
